By am. @Q4/@f A flor ne y Patented Dec. 24, 1929 srarss CLIFFORD F. PEER, @F CHESTERTOIX?, INDIANA SIDE BRASS FOR ROLLING-EIILL IIOUSINGS Application led August 15, 1927.

My invention relates to improvements in side brasses for rolling mill housings and it more especially appertains to the features pointed out in the claims.

The purpose of my invention is to provi le specially formed side brasses for rolling mill housings; that continuously scrape the hard grease toward the outer end of the roller necks; that by reason of a flanged projection which engages the outer diameter of a roller, at its ends, prevents the passage of grease from the bearings onto the surface of the roller; that provides a scraping erige of the brass which continuously engages the roller and neck; that by reason of the beveled upper surface a reservoir7 is provided wherein the hard grease may accumulate; and that may compensate for any reduction in diameter of re-dressed rollers by slightly adjusting th vertical position of the brass.

With these and other ends in view, I illustrate in the accompanying drawing such an instance of adaptation as will disclose the broad underlying principle of my invention without limiting myself to the specific details shown thereon and described herein.

Figure l is anlend elevation of a pair of rolls in their housing showing the location of the side brasses.

Fig. 2 is an enlarged elevation of the outside end of a side brass.

Fig. 3 is a plan view partly in section showing both ends of a roll.

Fig. 4l is a plan view of Fig. 2,

i; Fig. 5 is a top plan view showing an adjustable scraping member.

In rolling mill practice where hot rolls are employed it is found necessary to use what is known as a hard grease, of which one of the J .ingredients is soapstone. This grease is very frequently squashed out from the roller neck bearings on to the surface of the rolls. Even though the rollers are chilled the hard grease leaves indentations in the roll which are transferred to the sheet or other material passing between a pair of rolls. The result is an in-` ferior product and a damaged roll, or perchance a damaged pair of rolls.

It is not only a oase of a single pair of rolls being thrown out of commission on ac Serial No. 212,957.

count of such a mishap while one or both rolls are re-dressed, but there may be an entire group of associated rolls in a continuous train that must remain idle while the damage is rectified, thus causing large material losses. To overcome such losses and avoid the necessity of removing grease marks from rolls I provide the side brasses shown on the drawing. In carrying my invention into practice I may use any desired alternative construction that the varying exigencics of daily use may demand without departing from the broad spirit of my invention.

The form which I have found serviceable in actual use comprises a block of brass that is rectangular excepting that its upper face is beveled transversely and longitudinally, one side is made concaveto approximate the radius of the roll neck, and the inner end is flanged so as to approximately conform to the outside diameter of the roll. The brasses are made right and left hand so as to serve both ends of a roll. I They are placed on the down7 side of roller rotation', respectively for the upper roll on its entry side and for the lower roll on vits exit side` Diametrically opposite the special side brasses` ordinary brasses are placed in the housing to receive side strains and assist the top and bottom bearing brasses in holding the rolls in alignment wit-h each other.

In the drawing I have exemplified a housing l in which an upper roll 2 cooperates with a lower roll 3. These rollshave necks or spindles 5 which rotate against upper brasses g Gand bottom brasses 7 My improved form of side brasses is identified by the numeral 8. Ordinary side brasses areshown at 9. These side brasses rest in recesses 20 of the housing l. On the brass 8 a flange 10 is formed on its end. This flange engages the surface of the roll at 19 on a slight bevel (see Fig. 2) which continues toward the neck 5, at 12, along the roller end, as shown in Figs. 2 and 4 and the bevel continues along the fillet ll thence downward, lengthwise of the neck, at 17, terminating at the outside end of the brass at 18. On the beveled face, between 12 and 13 in the area 14 hard grease may accumulate. The flange l0 may have its leading toward the outer ends of the roll.

' side of face which is adjacent the roll surface curved at 15 to approximate the curvature of the roll. It is important that the scraping edge 19 engages the surface of rolls 2 or 3. rIhe side of the brass 8 adjacent the roll neck may also be made concave at 16 to approximate the radius of the neck 5.

In case a damaged roll is re-dressed, the slight change in diameter may be compensated for by an adjusting wedge 18 which will lower` the brass a small amount to bring the edge 19 into contact with the re-dressed roll surface, or by any other means. This may also be done, if desired, by making the flange 10 separately adjustable through the use of a wedge 18 or any analogous structure which will lower, or otherwise, bring the scraping point 19 against the roller surface to compensate for any change in diameter of the roll in case it is re-dressed.

An alternative expedient is shown in Fig. 5, in which flange 1() of Fig. 4 is replaced by a removable scraping member 23, which rests loosely in a groove 21. Any desired form of set screw 22 may be used to adjust the scraping member 23 toward the roll.

What I claim is:

1. In a rolling mill, a housing, a pair of rolls supported therein, a pair of beveled and flanged side brasses for each roll sait brasses being positioned adjacent the down the rolls rotation in simultaneous engagement with the surface of the roll near its ends, against each end and the necks of the roll to thereby direct grease away from the surface of the roll.

2. In rolling mills, a pair of housings, a

pair of rolls supported in the housings, and

a pair of side brasses cooperating with each roll, said brasses having beveled upper faces 3. In side brasses, a suitable member formed with a plurality of concave surfaces on one face thereof formed at different radii,

and a flange projecting from the end of the brass over the larger radius concavity, such concave surfaces engaging the neck and face of an adjacentroll to remove foreign sub stances therefrom as the roll is rotated in engagement with the concave surfaces.

b s s 1. As an article of manufacture, a side brass comprising a suitablemember having a projecting flange at one end thereof, a plurality of the side that slopes away of the member, and a top surface concave side and toward the other end of the brass, such concave surfaces engaging 'the neck and face of an adjacent roll to remove foreign substances therefrom as the roll is rotated in engagement with the concave surfaces.

5. In rolling mills, a pair of housings, a pair of rolls supported by the housings. a pair of right and left handed brasses engaging the different radii concave surfaces on from the flange toward the ends of a roll, projecting flanges from the brasses extending toward each other and engaging the surface of a roll, and beveled upper faces of the brasses leading downward toward the outer ends of a roll.

6. In rolling mills, a pair of housings, a pair of rolls supported bythe housings, a pair of right and left handed brasses engaging the ends of a roll whose upper surface is beveled downward away from the lengthwise center of the roll, and adjustable scraping projections supported by the brasses having their top surfaces sloping toward the ends of the roll.

In testimony whereof I affix my signature.
